Rotating decoration on gallows f42v

[nablator]

For the second example, what are those ain aiin aiiin at the end of lines? They seem not to have meanings, just some placeholders.

There are many ideas for what they might be, mostly based on the fact that they are so frequent (e.g., they are grammatical "articles", or conjunctions such as "and", etc.).

I think ChenZhe meant, what are they in You are not allowed to view links. Register or Login to view.? Not on every line, not on every page, it looks like there is a random number of "i" between 0 and 8 and sometimes a second "a". On f. 10v they seem to be merely decorative as they cover all the available space at the end of lines. On other pages they are absent (f. 9v, f. 10r) or present on some seemingly random lines (f8v, f9r). Weird.
